'\0' is the null character used to terminate strings in C/C++. //'\0'是null字符用于中止C/C++字符串 "\0" is an empty string. //"\0"是一个空字符串 NULL在stdio.h中定义: #if !defined(NULL) && defined(__NEEDS_NULL) #ifdef __cplusplus #define NULL 0 #else #define NULL ((void...
Finally, by using sstring_from_cstring we have a way of converting c strings into sstring: static inline sstring sstring_from_cstring(const char *cstring, bytes maxlen){sstring s={.ptr=(char *)cstring,};bytes len;for(len=0;len<maxlen;len++)if(cstring[len]=='\0')break;s.len=le...

I'm trying to call a function that takes a single string argument and returns an integer value. My test program below builds and runs, but generates an "access violation" when it calls the function in the C DLL. Is there something simple I am missing? I tried putting a C on the ...
Ans: The Null character serves as the string terminator in C because it allows C to identify the end of a string. When processing C strings, functions like ‘printf’ and ‘strlen’ rely on the Null character to determine the string’s length and terminate their operations accordingly. ...

Per SMPTE ST 377-1:2019, a "zero value" can be used to terminate a string. So, discard any data after the first null character found (if any). This has the same effect as the implementation for strings in regxmllib at: https://github.com/sandflow/regxmllib/blob/b47b0cdbd6dbf51...
